Applications
Built for 25G Ethernet, data center interconnect and 5G transport networks, this SFP28 module carries 25Gbps over MMF up to 400m@OM4/300m@OM3 per link. With its Duplex LC optical interface, the module works directly with the MMF infrastructure already installed in most facilities. For networks standardized on Cisco hardware, it is a drop-in equivalent of the SFP-10/25G-CSR-S.
Standards and Compatibility
Compliance: SFF-8472, SFF-8024, SFF-8431, SFF-8432, IEEE802.3by. For projects standardized on Cisco hardware, this product replaces the SFP-10/25G-CSR-S directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
Ordering Information
Our part number for this module is SFP-25GMCSR-85. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
Quality Assurance
Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
